Tread Wear Indicators; Life Of Tire - Chrysler 2007 PT Cruiser Convertible Instruction Manual

314 STARTING AND OPERATING

Tread Wear Indicators

Tread wear indicators are in the original equipment tires
to help you in determining when your tires should be
replaced.
These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 inch (2 mm). When the tread is worn to the
tread wear indicators, the tire should be replaced.
Many states have laws requiring tire replacement at this
point.

Life of Tire

The service life of a tire is dependent upon varying
factors including but not limited to:
• Driving style
• Tire pressure
• Distance driven
WARNING!
Tires and spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure.
You could lose control and have an accident result-
ing in serious injury or death.
